Abstract: A system is provided for universal public access communication adaptively integrating disparate modes of communication. At least one operator workstation is linked to a public access point for selective interactive communication with remotely disposed caller units in a plurality of selectable communication modes. A backend processing system for the public access point adaptively generates dynamic operator sessions for the operator workstation with the remote caller units. Each dynamic operator session selectively integrates one or more communication modes to preserve compatibility with external messages transmitted by the remote caller units. A plurality of logic service modules are each executable in the backend processing system for control a portion of the sessions, and corresponding gateways are configured to convert between external messages in the communication modes and internal messages having at least one predetermined format.
